β-Caryophyllene (11.0%) acts as a selective CB2 cannabinoid receptor agonist, modulating NF-κB inflammatory signalling and reducing pro-inflammatory cytokine expression.
Ref: class-extrapolation from β-caryophyllene; B216 Ch.14 β-Caryophyllene profile (Tisserand & Young 2014)
Whole Canadian bog myrtle EO demonstrated cytotoxic activity against A-549 lung adenocarcinoma and colon adenocarcinoma cell lines in vitro; chemistry profile varied with distillation time fraction.
Ref: Sylvestre et al 2005, Phytomedicine 12:299–304
α-Cadinol, a sesquiterpene alcohol present in bog myrtle EO, demonstrated specific activity against the human HT-29 colon cancer cell line in vitro.
Ref: He et al 1997a
Germacrone, a sesquiterpene ketone identified in bog myrtle EO, demonstrated activity against human breast cancer cells in vitro.
Ref: Zhong et al 2011
Traditional folk use across the circumboreal range of Myrica gale as an insect deterrent; volatile sesquiterpene and monoterpene fractions confer repellent properties explicitly recognised by B216.
Ref: Tisserand & Young 2014, Ch.13 p.711
β-Caryophyllene (11.0%) class-level anxiolytic activity via CB2 receptor engagement; β-myrcene (9.5%) contributes secondary sedative-calming tone at the monoterpene level.

AI-summary
No RCT-grade clinical trial evidence is available for myrtle-bog (Myrica gale) essential oil. The strongest available evidence is in vitro: Sylvestre et al (2005, Phytomedicine 12:299–304) demonstrated cytotoxicity of Canadian-distilled bog myrtle EO against A-549 lung adenocarcinoma and colon adenocarcinoma cell lines, with chemistry varying by distillation time fraction. Constituent-level in-vitro evidence includes He et al (1997a) confirming α-cadinol activity against HT-29 colon cancer cells, and Zhong et al (2011) confirming germacrone activity against breast cancer cells. All anticarcinogenic references are research context only and do NOT constitute therapeutic claims. Insect-repellent use is traditional folk use without controlled clinical study citation in B216. B216 records a triple safety data gap: no skin-sensitisation, acute toxicity, or carcinogenicity data found.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3-5 drops in 100 ml diffuser water | Forest-green balsamic aroma; limit session to 30–60 min, ventilate between. Limited global availability makes diffusion the most cost-efficient delivery route. |
| Topical massage | 1-2.5% in carrier oil (max 5% adult, framework default) | Stay within 5% adult max dermal (B216 framework default). Patch-test recommended; triple safety data gap. Avoid oxidised oil — refrigerate stock and use antioxidant-stabilised batches. |
| Skincare application | 0.5-1% in unscented base (leave-on); up to 2% rinse-off | Conservative dilution due to absence of skin-sensitisation data. β-Caryophyllene anti-inflammatory class-extrapolation may suit mature or inflamed skin. Avoid hypersensitive/damaged skin. |
| Direct inhalation | 1-2 drops on tissue or 3-4 drops in steam bowl | Steam bowl: inhale 5–10 min, eyes closed. Tissue: intermittent use. Supports respiratory comfort and grounding aromatherapy. |
| Insect-repellent formulation | 2-3% in light carrier oil or unscented lotion | Traditional folk use as insect deterrent within 5% max dermal cap. Reapply as needed. No controlled efficacy data available; complementary use only. |
